TONE-CLARIFIER FOB TALKING-MACHINES.

To all whom it may (on/em Be it known that I, FRANK Van Vines: MORSE, a citizen of the United States. residing at Minneapolis, in the county of i-lennepin and State of Minnesota. have invented certain new and useful Improvements in Tone-Clarifiers for Talking-iilachines; and I do declare the following to be a'full clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use he sanie.

This invention relates to improved means for clarifying and improving the tone of talking machines and other sound producers or reproducers.

The general object of the invention is to provide a device/of this character whereby the volume of sound will be increased. the tone clarified and the enunciation made more distinct and natural.

Another object of the invention to provide a clarifier of this character which will be simple, and inexpensive in construction and efiicient in operation, and which may be quickly and easily engaged with and re moved from its operative position.

\Vith these and other objects in view, the invention consists of certain novel features of construction and combination and arrangement of parts u hich will be more fully described and afterward specifically claimed.

In the accoin 'ianying drawings in which I have illustrated my invention in connection with a talking machine: Figure 1 is a side view of a portion of a graphophone having my invention applied thereto; Fig. 2 is an enlarged side view partly in section of the reproducer and the tone arm With the in vention arranged therein; Fig. 3 is a cross sectional view on the line of Fig. 2; Fig. 4 is a detail perspective View of the clarifier.

In carrying out my present invention. I employ a plurality of small tubes]. which are formed of suitable material. such as straws, or pressed paper from which artificial straws are made, any desired number of tubes being employed, such tubes decreas ing successively in length. The tubes are cut squarely across at one end and these squared ends are arranged. in the same dia metrical plane and the opposite ends of the tubes are beveled ofi or cut diagonally, as

shown mostclearly in Figs-if and The tubes are nested and secured together by a circular band 'hirh should he of very thin nniterial and with the tubes in the band in parallel relation, they and the band are firmly securei'l by means of glue or sin c.

While the device I121) be applied to any form of sound producing or reproducing machine, in the present instance. I have illustrated it as applied to the tone arin leading from the reproducer 1i a tallrin." machine.

In applying the attachment to this chine, the nested tubes are placed in the tone arm 3 between the reproducer and the amplifying horn, with the sotiared ends of the tubes arranged toward me repre-ducer or sound box. and the tapered ends 0 the tubes disposed adjacent the smaller eiid'ot the horn. with the ends of the tubes approxiniatcly filling the tone arm at this point.

Largely extended practical use of this vice has demonstrated that it magnifies sound and makes the tones clearer and more distinct, bringing out very clear sounds which were before practically ind 'iingnish able. While it have Sl'ktlllt'wlll) described construction and arrangement of the cone ponent parts of the device. and the position in which it is to be placed, it will be evident to those skilled in the art that changes and variations thcreinniay be made \vitl'iont departing from the spirit and scopeo'i invention as defined in the appended clain i-l'aving thus described my invent-ion, what I clainras new is: y

i. A tone clarifier for a talking machine .comprising a plurality of nested tubes of varying lengths adapted to be inserted in the. tone arm of the machine.

2. A. tone olaritier for a talking machine comprising a plurality oi nested tubes of varying lengths adapted to be inserted in the tone arm of the machine. the ends of the tubes at one end of the claritier being out off diagonally.

3. A tone clarifier for a talking machine comprisinga plurality of nested tubes of varying len ths adapted to be inserted in the tone arm or the machine, he ends of the tubes at one end of the claitier being cut oi? squarely in the same plane, and those atthe opposite end being cut oif diagonally.
